Microtubules and Neurodegeneration
Neurodegeneration refers to the progressive loss of structure and/or function of neu-rons often beginning at the synaptic distal ends of axons. Neurodegenerative diseases exhibit a broad range of clinical symptoms, which share several common pathological features. Prominent cellular features include the toxic aggregation of proteins that inhibit the protein quality control and the ubiquitin-proteasome machinery of the neuron, inflammatory responses, impaired ER calcium homeostasis, increased oxida-tive stress and microtubule defects.
In neurons, microtubules, actin filaments and neurofilaments compose the cytoskel-eton, maintaining cell polarity, architecture and morphology. Microtubules (MTs) are highly dynamic polymers formed of the tubulin and heterodimers. The GTP bound to -tubulin is stable and plays a structural function in the microtubule. The GTP bound to -tubulin may be hydrolyzed to GDP shortly after assembly into MTs, with GDP-tubulin being more prone to depolymerization.
MTs are polar structures with a labile plus end (favored for assembly and disassembly) and a stable minus end (less favored for these dynamics). Regulation of MTs polymeriza-tion is controlled by microtubule associated proteins, post-translational modifications of tubulin and , microtubule destabilizers (severing enzymes of AAA-ATPase type) and signaling molecules.
Mounting evidence sug-gests that deregulation of neuronal cytoskeleton function constitutes a key insult during the pathogen-esis of nervous system dis-eases. Microtubule mass is diminished and corruption of the microtubule polari-ty patterns (i.e. appearance of too many mal-oriented microtubules) and micro-tubule-mediated transport is observed during neuro-degenerative diseases, in-cluding Amyotrophic Lat-eral Sclerosis, Alzheimer, Hereditary Spastic Para-plegia, Parkinson’s disease and others.

Post-translational modifications (PTMs) are highly dynamic and often reversible processes where protein functional prop-erties are altered by addition of a chemical group or another protein to its amino acid residues. As key cytoskeletal proteins with roles in neuronal development, growth, motility and intra-cellular trafficking, tubulins and microtubules (MTs) are major substrates for PTMs. They include tyrosination/detyrosination,
2-tubulin formation, acetylation, phosphorylation, polyami-nation, ubiquitination, polyglutamylation and glycylation (see Figure). Most of these PTMs preferentially take place on tubulin subunits already incorporated into microtubules.
PTMs are involved in fine-tuning of interactions between micro-tubules and different MT-interacting proteins. Most axonal mi-crotubules are detyrosinated and further labeled with acetate and polyglutamate marks. By contrast, the unstable microtu-bules are enriched in carboxy-terminal tyrosination and devoid of glutamate tails. Detyrosination and polyglutamylation of MTs can selectively modulate the affinities and motility of molecular motors. Acetylation seems to control intracellular transport by regulating the traffic of kinesin motors. Microtubules PTMs de-regulation have impact on neuronal development and diseases.

Rab proteins, members of the small GTPase superfamily, are important regulators of vesicle transport via interactions with effector proteins and motor proteins. Rab1 and 6 are implicated in anterograde and retrograde trafficking in the secretory pathway. Recently, Rab1 has been shown to be involved in autophagy by helping the formation of the pre-autophagosomal isolation membrane (phagophore). Rab6 also functions as modulator of the unfolded protein response (UPR), helping the recovery from an ER stress insult. Rab6 is upregulated in Alzheimer’s disease brain.

Several studies show that the morphology of the neuron can be influenced by microtubule and actin filament cytoskel-eton dynamics, and that neurite outgrowth can be modulat-ed with stabilizing and destabilizing agents. Activation of the Notch signaling pathway results in stabilization of microtu-bules leading to regulation of axonal morphology, with thicker neurites, fewer branches and loss of synaptic varicosity. This Notch-dependent stabilization of microtubules is likely due to increase in acetylation and polyglutamylation of -tubulins, both of which are markers of stable microtubules.

Angiopoietin-2 in Cerebral Cavernous Malformations (CCMs)
H.J. Zhou, et al. (2016) recently found that enhanced secretion of ANGPT2 in endothelial cells contributes to the progression of CCM disease and is associated with destabilized endothelial cell junctions, enlarged lumen formation and endothelial cell pericyte dissociation. Treatment with an ANGPT2-neutralizing antibody normalizes the defects in the brain and retina caused by endothelial-cell-specific CCM3 deficiency.

Progranulin (PGRN) is a cysteine-rich protein, that shows mul-tifunctional biological activities, including major roles in can-cer, inflammation, metabolic disease and neurodegeneration, especially as a valuable biomarker for Frontotemporal Lobar Degeneration (FTLD). In the brain, PGRN is primarily expressed in mature neurons and microglia. Absence of progranulin in microglia causes increased production and release of multi-ple cytokines, suggesting that PGRN regulates microglia acti-vation. It is anticipated that PGRN affects microglial prolifera-tion, recruitment, differentiation, activation and phagocytosis, suggesting that PGRN plays a central role in the regulation of neuroinflammatory responses. PGRN serves as an impor-tant “brake” to suppress excessive microglia activation in the aging brain by facilitating phagocytosis and endolysosomal trafficking in these cells. In neurons, PGRN i) enhances sur-vival and neurite outgrowth through modulation of GSK-3 , ii) co-localizes in late endosomes and early lysosomes with the transmembrane protein TMeM106B, iii) co-localizes with markers such as BDNF along axons, iv) influences synaptic structure and function at synaptic and extra-synaptic sites, where it is secreted in an activity-dependent manner, and v) extracellular PGRN is endocytosed through the sortilin receptor and delivered to lysosomes. PGRN has also anti-inflammatory roles through inhibition of two Tumor Necrosis Factor Receptor family members (TNFR and DR3).

Netrin-1 is a guidance molecule that triggers either attraction or repulsion effects on migrating axons of neurons, interacting with the receptors DCC or UNC5 (A to D). It has been proposed that DCC and UNC5 are dependence receptors that, in the absence of netrin-1, promote apoptosis. This pro-apoptotic activity requires initial caspase cleavage of the receptor's intracellular domain. Netrin-1 is therefore a pro-survival factor acting by blocking cell death induced by its unbound receptors. Netrin-1 protects neurons from death during development and favors tumor epithelial cells survival in some types of cancers. It interacts with the orphan amyloid precursor protein (APP), a protein component of the amyloid plaques that are associated with Alzheimer's disease (AD). Netrin-1 also inhibits remyelination of neurons in Multiple Sclerosis (MS) (and other progressive demyelinating diseases) by inhibiting oligodendrocyte precursor migration. Recently, Netrin-1 has been described to be the 5th Element of classical iPS cell factors. Netrin-1 functions in protecting embryonic stem cells from apoptosis and addition of recombinant Netrin-1 improves the generation of mouse and human iPS cells (induced Pluripotent Stem Cells).

Pathological -Synuclein Transmission is initiated by the Receptor LAG-3
Parkinson's Disease (PD) is partially caused by amplification of a pathological -synuclein that spreads from cells to cells in the brain. Recently, X. Mao, et al. (2016) reported that -synuclein transmission and toxicity is initiated by binding to LAG-3 followed by endocytosis. Blocking this binding with an antibody to LAG-3 can reduce the toxicity of the -synuclein. This new discovery could help the future development of therapeutic drugs to slow down PD.

Neuroinflammation is an innate immune response in the CNS (Central Nervous System) against harmful and irritable stimuli such as pathogens, metabolic toxic waste or chronic mild stress that occurs in response to trauma, infections and/or neurodegenerative diseases. The main cell types contributing to the innate immune response are microglia, trafficking macrophages and astrocytes. These cells constantly survey the proximal environment through pattern-recognition receptors (PRRs) such as Toll-like receptors (TLRs), scavenger receptors (SRs) and NOD-like receptors (NLRs) (e.g. inflammasome complexes). These NLR receptors recognize not only exogenous pathogen-associated molecular patterns (PAMPs) but also endogenous modified molecules called damage-associated molecular patterns (DAMPs). After activation and release of immune molecules (e.g. cytokines), the innate immune system launches inflammatory and regulatory responses in order to counteract infection, injury and maintenance of tissue homeostasis. Although the evolutionary function is neuroprotective, innate immune responses can also promote immunopathology when they are excessive (e.g. chronic neuroinflammation). During chronic activation, the sustained exposure of neurons to pro-inflammatory mediators can cause neuronal dysfunction and contribute to cell death. As chronic neuroinflammation is observed at relatively early stages of neurodegenerative diseases, targeting the mechanisms that drive this process may be useful for diagnostic and therapeutic purposes.
Neuroinflammation is mediated by protein complexes known as inflammasomes. Inflammasomes function as intracellular sen-sors for infectious agents as well as for host-derived danger signals that are associated with neurological diseases, including men-ingitis, stroke and Alzheimer’s disease (AD). The inflammasome can be activated in the CNS under diverse conditions that trig-ger inflammation, including acute infection (e.g. viruses, bacteria), chronic sterile inflammation (e.g. misfolded proteins such as amyloid- , -synuclein and prion protein) and acute sterile injury (ATP excess) (see Figure). Assembly of inflammasomes (NLRP1/2/3 and NLRC4/IPAF) activates pro-inflammatory caspase-1, which then cleaves the precursor forms of pro-inflammatory cytokines IL-1 and IL-18 into their active forms. These pro-inflammatory cytokines promote a variety of innate immune processes associated with infection, inflammation and autoimmunity, and play an instrumental role in the onset of neuroinflammation and subsequent occurrence of neurodegenerative diseases, cognitive impairment and dementia. NLRP1/2/3 and NLRC4/IPAF inflammasomes may also have a role in the etiologies of depression, Alzheimer’s disease (AD) and in metabolic disorders, such as Type II diabetes, obe-sity and cardiovascular diseases that have been shown to be co-morbid with psychiatric illnesses.

are the secretion of the mature forms of caspase-1 and interleukin-1 (IL-1 ) from cells

tory caspases and cytokines of the IL-1 family (IL-1 , IL-18 and depending on the stimulus
also IL-1 ). Several inflammasomes have been described which contain different sensor
proteins such as NLRP1 (NALP1), NLRP3 (NALP3), IPAF (NLRC4), NLRP6 (NALP6), NLRP12
(NALP12), RIG-I and AIM-2 (absent in melanoma 2). Most of these inflammasomes
require the adapter protein Asc (apoptosis-associated speck-like protein containing a
caspase recruitment domain) to recruit caspase-1 to the inflammasome complex. Upon
binding to the inflammasome caspase-1 is cleaved and activated, leading to cleavage
of its various targets and causing maturation and secretion of the pro-inflammatory
IL-1 . Inflammasomes can be activated through multiple signals including live bacteria,
microbial toxins, xeno-compounds, particulates cytoplasmic pathogen-associated
molecular patterns (PAMPs) and/or endogenous danger signals (DAMPs).
Inflammasome activity has been causally linked to the induction of numerous inflamma-
tory responses, which can be either beneficial or harmful to the organism. Beneficial
responses arise by maintaining homeostatic tissue function (detection and repair of
tissue damages after trauma or pathogen invasion). Among the harmful inflammato-
ry responses are particle-induced sterile inflammation, caused by host-derived parti-
cles such as monosodium urate (MSU) crystals, which are involved in the pathogenesis
of gout, as well as environmental and industrial particles such as asbestos, silica and
metallic nanoparticles, which induce lung inflammation upon inhalation. Accumulating
evidence also implicates inflammasome activity in numerous other diseases, including
cancer and the development of metabolic diseases (like type 2 diabetes, atherosclero-
sis), some neurodegenerative diseases (like Alzheimer, Prion, Parkinson), autoimmune
diseases (such as multiple sclerosis) and inflammatory bowel diseases. Beneficial effects
for the host include the enhancement of vaccine efficacy.
